BUB-NEE APPLIANCE Application filed September 28, 1929. Serial No.395,829.

This invention relates to an appliance constructed for directassociation with a gaseous fuel burner, for instance of the typeemployed in the construction of domestic gas ranges,

stoves and the like.

The purpose of the invention is to provide a simple and inexpensiveappliance in the nature of an attachment to be placed directly upon theapertured burner, the same being such as to permit it to be locatedbeneath an overlying utensil supporting grid and of a specialconstruction to enhance the heat productive properties of the burner.

More specifically stated I have evolved and produced a burner attachmentwhich is con.- structed to concentrate the flame beneath the center ofthe utensil and to further distribute peripheral portions of the flameto cause said portions to impinge on the bottom of the utensil withoutplaying up and around the sides, to minimize soot deposits on the lowerpart of the rim portion of the utensil.

I further propose the provision of an ap pliance which comprises aplurality of ring like vertically spaced elements formed into asubstantially frusto-conical body, to minimize accumulation of greaseand deposits around ports of the burner, to reduce extinguis ring of theflame by blustering air cur rents, and to otherwise fulfill therequirements of a device of this kind.

Other features and advantages will become more readily apparent from thefollowing description and drawings:

In the drawings:

Figure 1 is a top plan view with portions broken away to disclose theassociation of the parts more clearly.

Figure 2 is a section through a gas burner with the appliance seatedthereon.

Referring to Figure 2 of the drawin will be seen that the referencecharacter designates the top of a domestic gas range or stove, whilelindicates the removable utensil supporting grid.

The reference character 5 designates gen erally a conventional gas stoveburner provided with. a multiplicity of gas discharge.

ports 6. The appliance is indicated generally 5 by the referencecharacter 7 and comprises a single metal casting including a base ring 8which is of curved cross section to enable it to rest on and conform tothe shape of the crown portion of the burner 5. The reference characters9, 10 and 11 designate similar rings wh'ch are arranged in verticallyspaced ruperposed relation, the ring 10 being smaller in diameter thanthe ring 9, and the ring 11 being graduated still smaller. The verticalcircumferentially spaced posts 12 serve to connect the quartet of ringstogether in assembled relation. This arrangement defines a central flamedischarge opening 13 at the top. In addition it defines annularperipheral flame discharge openings between the marginal portion of thesuperposed rings 8 to 11, inclusive. Thus, the flame takes the tortuousdischarging passages indicated by the arrow in Figure 2.

It will be observed that the device is supported directly on the burnerand that it is of a height to pe mit it to be disposed beneath the gridon the stove. Thus there is no like lihood of the appliance beingaccidentally knocked off of the burner. Once more the base ring conformsto the shape of the burner, thereby rests snugly and firmly thereon,being disposed outwardly of the gas ports and thereby not interferingwith the flame jets.

hen too, the graduated vertically spaced and superposed arrangement ofthe annuli or rings serves to prevent clogging of the ports by droppinggrease and extraneous matter from boiling utensils and the like.Moreover, the arrangement and cooperation of these rings serves as aflame guard in that it prevents the draft from extinguishing the flame.Then again, as before stated, the principal part of the flame isconcentrated and discharged through the opening 13 while annular flamejets are formed around the marginal portions of the superposed rings.This brings about an entirely different equalization of the flame andprevents the sides of the utensil from blackening. By thus confining theflame and at the same time distributing it, effective results areinsured.

It is thought that by considering the description in connection with thedrawings, a clear understanding of the construction, features andadvantages of the invention will be had, therefore, a more lengthydescription is regarded as unnecessary. I
